We need to clean air ducts in a building where part of the air duct have been
insulated (from the outside) with blue-asbestos. Removing the asbestos would
involve huge costs and we have a time limit. I am asking is there anyt other way
to clean the air ducts. It probably costs a lot too but at least we don't have to
redo the ceiling. The air ducts are 1.5 ft x 1.5 ft rectange shaped and made of
metal sheet.
